Try doing sets of pull-ups, various weights, and walking with your crutches in between nonstop for a couple of hours a day. Should get your heart rate up, and keep it up if you work at it with enough intensity.

One really fun impromptu exercise to do on crutches is to lean up against a wall and do leg lifts; sets of ten or twenty. When I was injured I made a point of doing at least 150/day, and it REALLY improved abs and core. Combine this with all the other upper body, and you'll be super strong by the time you have your leg back.

I was non-weight-bearing for two months after a knee surgery a couple of years back, followed by a month of partially-weight-bearing-with-crutches. While the suggestions you got here are good, I found it to be too frustrating and boring, and ultimately didn't do much other than the PT exercises and some pushups. The PT did include a fair bit of core exercises.

Once I was able to partially load the leg, I did a month of hangboard workout, Rock Prodigy style (I thought i could do it earlier, but discovered that it was not possible to do hangboard with full non-weight-bearing if you can't bend the knee... but in your case, since it's the ankle that is broken, you cna bend that knee, and so you are in better spot than I was...).

Cardio fitness declines fast, but also comes back fast, the things you would be doing in the next couple months are likely not enough to maintain your cardio fitness, anyway. But if they keep the boredom at bay... go for it.

I was in a similar situation recovering from a tib/fib fracture in an ice climbing fall in 2009. I found that my cardio fitness came back relatively quickly after I was healthy enough to do normal activity; various "creative" efforts I undertook while healing were generally frustrating or "fussy" in such a fashion that I couldn't really achieve anything on the regular that I felt was fitness-preserving. I mostly spent my energy focusing on other things (work) and tried to watch my diet a little more carefully.

I'd recommend some real basic hangboarding that feels like "maintenance" to avoid losing a lot of finger strength. Also accept that it'll be a couple of month on-ramp once you come back.

To each their own, but I think the isolated leg stuff seems like it could be whack-a-mole by elevating risks associated with having imbalances.

Great ideas. Thanks! My biggest challenge is going to be stay off it. The put a soft splint on today because its still too swollen to cast or do CAT scan (may need screws)

That things lasted about 2 hours and I ripped it off. I couldn't take it. There is my biggest chanllenge, the mental aspect of not pushing and trying to walk or use it. Gonn abe hard but I keep telling myself it will just be longer.

But this soft thing was just to bulky I mean like Herman Munster shoes it had to go!

John, I'll say this once. The mental part is the hardest. Keep it on, the rigid cast will be worse. Prepare yourself for the long haul and do it right the first time. I was told to wear an e-boot for a month 24x7. I didn't. When that didn't work they put me in a cast for another month. Don't be stupid like me and do it twice or heal more slowly because you didn't do it right. OK, taking my responsible shmuck hat off now; do what you want and heal on the timeline you decide to take. :)

Thanks Eric. I realized I had to do what doc said also, and reapplied it shortly after. Just have to accept the deal and pray 8-10 weeks go by quick. In the meantime work upper body, do whatever cardio I can (I think stationary bike may work at some point) go real low calories and just hang tough.

I've always taken adversity in my life and turned it around, using the frustration, pain, whatever situation it may be (my divorce comes to mind) and turned that negative energy into positive energy and improve myself and my life. This will be no different. I'll find a way to take this and make it a psotive as well. Thanks for writing!

My girlfriend is xfit nut and she suggested a modified xfit routine similar to what wheelchair folks use for xfit. Great Idea! I googled it and on youtube there are some people in chairs (for life not just broken leg like me) doing stuff that would put normal two legged people to shame. Just goes to show what determination and the human spirit can accomplish.

Yeah, the adaptive climbing folks at Brooklyn Boulders really put my ankle sprain in perspective. I can't complain that I have to top rope routes with easy footwork and lower carefully for a few weeks when these guys are campusing 5.9 because they don't have use of their legs.
